Title: Tension measuring instrument for power transmission line
Inventor: SUZUKI YOSHIO
IPC: G01L5/04
Filed: 1990-05-21
Abstract: PURPOSE:To reduce the size of the instrument and to improve the handling on a steel tower without decreasing the measurement accuracy by finding an arc angle from a contact detection signal which is outputted corresponding to the length with which an electric conductor is in contact with a pulley. CONSTITUTION:A sensor 9 is so formed that rubber as an elastic insulating material is sandwiched between two metallic plates and when the electric conduc tor 20 contacts the pulley 1, the two metallic plates contact each other with the contacting pressure; and the sensor outputs the contact detection signal corresponding to the length to which the electric conductor 20 is in contact with the periphery of the surface of the pulley 1. Then one metallic plate made of a high-resistance material contacts the other metallic plate which is relatively small in resistance to vary in resistance value corresponding to the contact length. The variation in the resistance value is inputted to a computing element 8 stored previously with an accurate resistance value corresponding to the contact length between both the metallic plates and the arc angle is calculated from the highly accurate arc length calculated by comparative arithmetic, so the instrument is reduced in size and its handling is facilitated.

Title: Scroll compressor
Inventor: SATO EIICHI
IPC: F01C17/06
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To insure lubricating oil in the sliding parts of an Oldham's coupling by providing communication holes between the respective slide faces on the load side and the antiload side, on the keys engaging with the back face and the frame side of the turning scroll of an Oldham's ring. SOLUTION: Two keys 15a are provided in the direction of 180 deg. on the turning scroll side, and two keys 15b are provided similarly in the direction of 180 deg. on the frame side so as to be deviated positions from the keys 15a by 90 deg.. In the perpendicular directions to the respective sliding directions X, Y of the respective keys 15a, 15b, communication holes 21 communicating the load side slide faces F and the antiload side slide faces are provided. Thus, lubricating oil enclosed in the communication holes 21 hardly leaks outward, because the gap between between a key groove 11a and the key 15b is very narrow so as to be several tens μm and viscous resistance exists in oil. Consequently, abnormal abrasion due to the shortage of oil can be prevented from generating in restarting the compressor, and compression performance and reliability for sliding can be insured.

Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To ensure a sufficient gettering site by forming a gettering layer in a part in contact with an insulating layer of a supporting substrate wafer in an SOT wafer. SOLUTION: Two silicon wafers are prepared. One of the wafers is used as a supporting substrate wafer B and the other is used as an active layer wafer A. A silicon oxide film SiO2 with a predetermined thickness is formed on the surface of the active layer wafer A. A mirror surface of the supporting substrate wafer B is irradiated with a laser beam. A defect to be a specified gettering site is formed within a range G of a predetermined depth from the surface of the silicon wafer B. The surface of the gettering layer is superimposed on the silicon oxide film, and the silicon wafers A, B are adhered to each other at a room temperature under an atmospheric pressure. Then, predetermined bonding heat treatment is performed. Thus, there is no possibility of re-emitting contaminant, and warping of an SOI wafer may be reduced. Also, a sufficient gettering site may be ensured.

IPC: G03G15/00
Filed: 1987-05-27
Abstract: PURPOSE:To rapidly detect the abnormality of a lifting device by starting the measurement of time simultaneously at the start of the driving of an electric driving means, and energizing a notifying means if a defined electric signal from a position detecting means tails to be detected before the measured time reaches a time corresponding to the condition of a time changeover means. CONSTITUTION:An error signal is issued if the time from the start of the drive of an electric motor 65 till the detection of the pulses of a rotary encoder 65a exceeds the contents of T1, further, if the time until an upper limit position sensor PS2 is turned on exceeds the contents of T2, or if the number of pulses of the encoder 65a which is detected after the drive of the electric motor 65 is stopped exceeds the contents of N1. The values stored in these T1, T2, and N1 are set to the minimum values which can distinguish the existence of errors respectively. For example, the value of the T2 is a value which corresponds to that a minute surplus time is added to the theoretical longest time which is required at the time of driving to the upper limit from the turned-on condition of the lower limit position sensor under a condition that a recording sheet does not exist on a tray 61. And, this value is varied by the frequency of a power source.

IPC: G03B27/46
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To correct chromatic aberration after a photographing action is executed even when the photographing action is executed by a photographing lens having the chromatic aberration by forming a color image by executing sharpness processing by making it different every color when the images of respective colors are formed based on the respective color image signals of blue, green and red. SOLUTION: The light beams of three colors of blue, green and red are photoelectrically concerted by a CCD line sensor and inputted to an image processing part 2. By the processing part 2, the image signals of three colors are converted to digital data and prescribed image processing such as shading correction is executed. Thereafter, the image processing for correcting the chromatic aberration is executed. When the axial chromatic aberration is corrected, it need not be corrected as for the image signal of green but it must be corrected as for the image signals of blue and red causing out-of-focus and the lowering of sharpness. Then, the sharpness processing, that means, the contour emphasizing image processing using a dither method is executed with respect to the blue image signal and the red image signal. As the result, the image becomes sharp and more excellent.
